T @ZZ whom it may concern/ i. A A, s

Be it known that I, MAXPSCHORR, a citizen of the United States; -residing 'at Marxville, in the county ofDane and State of Wisconsin, have invented a new'and useful Spark- Extinguisher, of which the followingis a specification.

My invention relates to a vmeans for extinguishing the sparks in the smoke-stacks of traction and farm engines; and the object that I have in view is to providea simple and inexpensive construction which may be readily fitted to a smoke-stack for the purpose of j preventing sparks passing from the re-box to the smoke-chamber and at the same time wholly obviate any checking or interruption of the draft, thus obviating the clogging ofV the working parts of the extinguisher audof drawings.

My invention is capable of application to or adjustment inthe smoke-stack of any or dinary traction or farm engine withoutrespect to thediameter of the stack andwithout requiring remodeling ofthe stack, the

Y numeral 1 designates thesmoke-box, 2 the smoke-stack, and 3 the exhaust-nozzle, of an ordinary traction or farm engine. No novelty l for these parts isclaimed herein, and they may be of the usual or any preferredconstruction familiar to those skilled in the art.

My attachment for extinguishing sparks and facilitating the draft through the smoke.-l

Lstack is adaptedgto.beinserted into the stack and have connection with the eXhaustr-nozzle. VlnrThe invention consists of a cylinder 5,' a 'small cylinder or tube 6, a cone 7 and two 'setsbf arms orlbraces that serve to' unite the lower cylinder G and thecone 7 to the respective ends of the cylinder 5 in a manner to have the cone and lower cylinder in vertical axial alinement with each other.

The cylinder 5 consists simply of an openended' elongated tube of metal, and it is of a diameter less than that of a sInoke-stack in which the attachment is to be placed. In practice I prefer to make the cylinder 5 about two and one-half inches in diameter, because I have found that this size of the cylinder is Any variation in the length of the engine smoke-stack is compensated for by changing the length of the cylinder 5, according as may be desired to secure the best results; but it is not necessary from a practical standpoint to vary the diameter of said cylinder 5. Y j

- The lower tube 6 is arranged below the lower open' end of the cylinder 5 and at a suitable distance therefrom. This lower tube is of muchI smaller diameter than the cylinder 5, and itis-"rigidly fastened toT said cylinderby the lower yseries of arms 9, which maintain the tube'V in central or axial relation tothe sufficient toenable it to be u sed in connec- `tion with smoke-stacks which may vary in diameter.

cylinder 5.- jThis?tube' is'spaced-below the I cylinder kto permitthe intoductio'nv of the;-

exhaust-nozzle 3 of the engine, as shown by Fig. 1','so.that the exhaust-steam will pass from the nozzle into and through the cylinder 5 of theattachment, and the described mea-nsf for attaching the tube to the cylinder provides large openings or spaces between said cylinder and the tube forthe free passage of the smoke and other products of combustion into the cylinder.

-The cone 7 is arranged in such relation to the upper open end of the cylinder that the apex thereof projects well down into andbelow said open end of the cylinder. In practice I prefer to have thelower part ofthe cone extend into the cylinder for a distance of about two inches. Said coneismaintained IOO in fixed axial relation to the cylinder by the upper series of arms S, which are spaced at suitable intervals around said cone and cylinder and are united at their ends in a suitable way to the cone and cylinder. The cone llares upwardly from the axial line of the cylinder, so as to divide the draft and insure uniformity to the volume of smoke and exhaust-steam which may )ass through the cylinder and smoke-stack, and by employing the series of spaced arms or braces large openings or spaces are left between the cone and cylinder to insure free and unobstructed passage of the smoke and exhaust-steam.

My attachment has all of its working parts secured or united together in a durable manner.

To use the attachment in a smoke-stack, it is only necessary to lower the same into the stack for the lower tube or cylinder to fit on the exhaust-nozzle, which is thus made to serve as the means for holding the attachment in place,particularly against lateral displacement. lhe cone of the upper end of the attachment occupies a position below the open upper end of the smoke-stack. IVhen the attachment is used in stacks of large diameter, it is held against displacement by suitable means-as, for instance, by radial braces or arms attached, respectively, to the smoke-stack and to a part of the attachmentas, for instance, the cylinder 5 thereof.

In the practical service of the engine it will be found that the exhaust-steam passing into the cylinder creates an upward suction or draft, which is divided and deflected by the cone sustained at the upper extremity of the cylinder.

The described construction of the sparkarrester prevents any cinders or sparks from passing from the lire-box into the stack, as they are kept in the lire-box, and at the same time a free passage is insured for the smoke and gaseous products of combustion.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

'lhe combination with a smoke-staek, and an exhaust-nozzle below said stack, of an insertible spark-arrester slipped into the stack to rest upon the exhaust-nozzle and comprising an elongated tube, 5, of less diameter than the stack, a short lower tube, G, situated below the tube, 5, and arranged in the plane of the Vertical axis thereof to rest upon the exhaust-nozzle, the inclined arms which join the tubes rigidly together and are spaced to provide large openings for the passage of the products of combustion to the elongated tube, au inverted conical defiector, 7, with its apex extending into the elongated tube, and arms which join the deflector to the tube, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

MAX ISCIIORR.
